China’s population stood at 1.41175 billion people as of the 2020 national census, according to data released by the National Bureau of Statistics (NBS) of China. This figure, announced in May 2021, represents a growth rate of 0.04% per year between 2010 and 2020, the lowest growth rate recorded since the start of the modern census cycle in 1953.
The China national population census serves as the primary tool for the central government to track demographic shifts, allocate resources, and adjust social policies. While the 2020 count confirmed China’s status as the world’s second-most populous nation, the data revealed an accelerating trend toward an aging society and a shrinking workforce.
These modern surveys are the evolution of a millennia-old tradition of state tracking. From imperial dynasties using registers for tax collection and military conscription to the current digital-first methodology of the NBS, the census has remained a cornerstone of Chinese statecraft and social control.
How the 7th National Population Census reflects China’s demographic shift
The seventh national census, conducted in 2020, provided the first comprehensive look at the long-term effects of the one-child policy and shifting urban migration patterns. According to the National Bureau of Statistics of China, the population aged 60 and over reached 18.7% of the total population, totaling 264 million people.
This aging trend creates a shrinking labor force, which economists suggest could hinder long-term GDP growth. The census data showed that the working-age population (ages 15 to 64) has continued to decline, a trend that began around 2012. This shift has prompted the Chinese government to transition from the one-child policy to a two-child policy in 2016, and eventually a three-child policy in 2021, to stabilize the birth rate.
Urbanization also reached a new milestone. The 2020 census reported that 65.1% of the population now lives in cities, an increase from 56.5% in 2010. This migration from rural villages to urban centers has fundamentally altered the social fabric of the country, creating a massive “floating population” of migrant workers who live in cities but maintain legal residency in their home provinces.
What the National Bureau of Statistics reports on population growth
The NBS utilizes a combination of traditional door-to-door interviews and electronic data collection to verify population counts. For the 2020 cycle, the agency integrated “big data” from administrative records to reduce the costs and time associated with physical surveys. However, international observers and some demographers have occasionally questioned the precision of these figures, citing the political pressure to meet specific growth or stability targets.
A critical data point from the 2020 census is the gender imbalance. The NBS reported a sex ratio of 105.1 males for every 100 females. While this represents a slight improvement over previous decades, the imbalance remains a legacy of cultural preferences for male children and the restrictive birth policies of the late 20th century.
The government uses this data to plan infrastructure, such as hospitals and schools, and to determine the distribution of pensions. As the 60-plus demographic grows, the NBS data has become central to debates regarding the legal retirement age, which remains among the lowest in the world for both men and women.
How ancient imperial censuses shaped Chinese governance
The practice of counting the population is not a modern adoption in China; it is one of the oldest bureaucratic traditions in human history. During the Han Dynasty (206 BCE – 220 CE), the imperial government maintained detailed household registers to ensure efficient tax collection and to draft peasants for military service. These records were essential for the centralized control of a vast and diverse territory.
Throughout the Tang and Song dynasties, censuses were used to manage land distribution and grain reserves. These historical records often focused on “mouths” (individuals) and “households,” providing the state with a mechanism to monitor the movement of people and prevent tax evasion. The ability to count the population was viewed as a symbol of the Emperor’s mandate and his control over the realm.
The transition to modern statistical methods began during the Republic of China era in the early 20th century, as the state sought to adopt Western scientific methodologies for social planning. This laid the groundwork for the first formal census of the People’s Republic of China in 1953, which established the ten-year cycle that continues today.
Why the “floating population” complicates data collection
One of the most significant challenges for the China national population census is the hukou system, or household registration. This system ties a citizen’s social benefits—including healthcare and education—to their place of birth. When workers move to cities for employment, they become part of the “floating population,” meaning they reside in one city but are legally registered in another.
According to reports from the World Bank, the hukou system creates a dual-society structure in urban areas. For census takers, this creates a verification nightmare. Individuals may be counted at their place of work or their place of registration, leading to potential double-counting or undercounting of marginalized migrant groups.
To address this, the NBS has implemented “de facto” counting methods, where individuals are recorded where they actually reside on the night of the census, regardless of their hukou status. This approach provides a more accurate picture of urban density and the actual demand for city services, even if it conflicts with official registration data.
The tension between legal registration and actual residency remains a primary driver of social inequality. Migrant workers without local hukou often lack access to public schools for their children, a fact highlighted by the demographic data showing a high concentration of school-aged children in urban areas who are not registered residents.
Comparison of Recent Population Trends
The following table summarizes the key shifts observed between the 2010 and 2020 national censuses based on NBS data.
| Metric | 2010 Census | 2020 Census | Trend |
|---|---|---|---|
| Total Population | 1.34 billion | 1.41 billion | Slowing Growth |
| Urbanization Rate | 56.5% | 65.1% | Increasing |
| Population 60+ | 13.3% | 18.7% | Rapid Aging |
| Avg. Annual Growth | 0.6% | 0.04% | Sharp Decline |
These figures illustrate a nation in the midst of a profound demographic transition. The sharp decline in the average annual growth rate suggests that China may reach its population peak sooner than previously projected by international agencies.
The next major checkpoint for China’s demographic tracking will be the 2030 National Population Census. Until then, the government relies on annual sample surveys and administrative data from the Ministry of Public Security to monitor population fluctuations and the effectiveness of new pro-birth policies.
